13 Claims.

This invention relates to improvements in machines for wrapping or labeling rolls such as toilet paper, and the principal object of the invention is to provide a machine of this character of generally improved characteristics.

Another major object is to provide an improved machine for applying wrappers or labels to rolls without use of pick-up" glue applied to the roll itself. I

With reference to Figs. 1 and 2 of the drawings, the illustrated machine comprises a base I, at the rear end of which is supported a pedestal 2, in the upper end of which is fixed a stub shaft 3. Immediately adjacent the pedestal 2 the shaft 3 carries a fixed cam 4; and fixed to the forward end of the shaft 3 is a plate 5, the function of the aforesaid cam and of the plate 5 being hereinafter set forth. Mounted for rotation on the shaft 3 intermediate the cam 4 and the plate 5 is a spider 6 having at its forward end radially projecting arms I, each of the arms having at its outer end a bearing 8 in which is slidably supported a pin 9. As illustrated in Fig. 3, the pins 9 are slotted longitudinally at I l for reception of a retaining pin l2 in the bearing 8, which pin limits the extent of the sliding movement of the pin 9 in the bearing. The pins 9 are hollow for reception of a spring l3 which by reaction with the pin l2 and the pin 9 holds the latter resiliently in contact with the forward working edge of the cam 4, and each of the pins 9 carries at its rear end a cam roller 14 for anti-friction contact with the cam. The cam 4 carries at the top a plurality 5 of forwardly projecting arms l5 which constitute supports for a segmental plate 16, this plate being secured to the forward ends of the arms; and a corresponding segmental plate H, see Figs. 1 and 2, is supported in alignment with the plate It on arms l8 which project forwardly from the upper side of the plate 5. As illustrated, the plates l6 and I1 are located at opposite sides of the path of the pins 9, and the outer ends of the pins project normally beyond the outer faces of the said plates.

Rotation of the member 6 is effected by means of a gear l9 which meshes with a pinion 2| on a shaft 22, which shaft is journaled in the pedestal 2 and projects forwardly through the interior of 20 the cam 4. The rear end of the shaft 22 may be connected through the medium of a clutch 23 with a suitable source of power (not shown).

In the operation of the machine for wrapping or labeling rolls of tissue paper, as hereinafter 25 set forth in detail, the rolls are placed individually on the projecting ends 9a of the pins 9, see Figs. 1 and 3, and are carried by rotation of the member 6 through a series of operations in which the labels or wrappers are applied, after which the rolls are removed automatically from the pins and deposited in a suitable container on a conveyer.

With reference to Fig. 2 of the drawings, the member 6 in the normal operation of the machine rotates in the direction of the arrow, and the rolls shown in broken lines and indicated by the reference numeral 24, are placed on the pins 9 as they progressively advance to a position between the plates l6 and H, the inner ends vof the rolls engaging the outer faces of the plates l6 and I1 as shown in Figs. 1 and 3. As the pins advance the rolls 24, the outer faces of the rolls are brought into engagement with a roller 25 mounted on a bracket 26 projecting from the outer face of the plate 5, the roller 25 being so positioned with respect to the plates l6 and I1 that the rolls are compressed suflici'ently to insure a proper normal positioning of the convolutions of paper between the end faces of the roll. The rolls are then brought into contact with the curved surface of a plate 21 supported on a bracket 23 also secured to the outer face of the plate 5, this contact of the roll with the plate 21 F effecting a rotation of the roll on the pin 9 which end of the tissue paper.

has the effect of winding up in the roll anyloose At this point also the roll engages'a roller 23, at the outer end of an arm 3| on a rock shaft 32 journaled in one of the arms I 5, which shaft carries a second arm 33 which is operatively connected through a rod 34 with a clutch 35, this clutch being operatively associated with a shaft 36 journaled in brackets 31 on the base I and having a driving connection through a chain and sprocket assembly 33 with the shaft 22. The clutch 35, which is of the one.- revolution type, functions to connect the shaft 36 with an aligned shaft 39. The clutch is normally disengaged and is held in disengagement through the medium of a lever 4|, see Fig. 8. When as previously described one of the rolls 24 engages the. roller 23 and thereby rocks the shaft 32, the lever 4| is elevated, as shown in Fig. 8, permitting the clutch 35 to engage and to thereby connect the shaft 39 with the shaft 36. As the roll 24 passes from under the roller 23, the latter with its lever 3| is permitted to drop to its original position, which returns the lever 4| to its'operative position wherein following one full revolution of the shafts 36 and 39, it again functions to disengage the clutch 35, which interrupts the rotation of the shaft 39. Clutches'of this type are well known in the art and form no part of the present invention. It will be apparent from the foregoing that as each roll in its movement on the member 6 passes the position of the roller 23, the shaft 33 is set in motion fortone full revolution, and is again brought to res Positioned in the path of the rolls 24 at a point below the roller 29 and the plate 21 are a pair of oppositely arranged hinged plates 42 and 43, see Figs. 9 to 14, inclusive, which constitute supports for the mid section of a wrapper or label 44 and which are adapted to be depressed on their hinges 4,5 and 46 by the downwardly moving roll. In Fig. 9, the roll 24 is shown approaching the plates 42 and 43, and the manner in which these plates are depressed, by the roll is shown in Figs. 10 and 11. Depending from the plates 42 and 43 are hinged pins, 41 and 43 respectively, which pass through openings in guide plates 49 and 5| on the fixed structure 53 of the machine. As the pins 41 and 43 are depressed with the plates 42 and 43 and as illustrated in Fig. 10, they are adapted to engage the projecting arms 52and 53 of a pair' of locking hooks 54 and 55 pivotally mounted in the machine, which normally respectively engage and support the weighted arms 56 and 51 of pivoted bell crank levers 53 and 53, as shown in Fig. 4, which illustrates the mounting of the lever 53. These levers are mounted on stub shafts 6| which are supported in bosses 63 on the base extension la. The other normally upstanding arm 62 of the lever 53 carries at its upper end a brush 63, while the corresponding arm 64 of the lever 59 carries a pad 65. Adjacent the upper end of the arm 64 and inposition to be engaged by the pad 65,

downwardly toward the position in which it is shown in Fig. 11. As the roll 24 moves downwardly between the plates 42 and 43, it carries with it the label which partially enfolds the roll as illustrated, and the brush 63 and the extremity of the arm 64 by engagement with the outer face of the label tend to wipe the free endsashereinafter set forth, that end of the label at the side engaged by the brush 63 is eventually moved by the brush, as shown in Fig. 12, into contact with the adhesive-loaded pad 65, so that the inner face of the label at that end is provided with suflicient adhesive to hold the label in place on the roll when the movement of the latter and the action of the brush 63 have brought the adhesive-receiving end of the label into overlapping contact with the other end of the label, as shown in Fig. 13. It will be noted that in this series of operations the end of the label engaged by the arm 64 is held by that arm against the face of the roll until the other end of the label has been brought down by the action of the brush 63 into close proximity to or into contact with the opposite end of the label, so that there is no tendency I for the wrapper to leave or loosen upon the roll move in a circular path with the gears 63 and 69,

as indicated by the arrows. As shown in Figs. 1 and 4, the gears 68 and 69 are journaled on studs secured in the base extension la. These gears are driven intermittently from the shaft 39, which shaft as shown in Fig. 1 carries a gear 13 which meshes witha gear 14,\see Fig. 16, the gear 14 in turning meshing withthe gear 69. The gear 14 also meshes with a gear 15, and this gear meshes with the gear 63. Both of the gears 14 and 15 are joumaled, like the gears 63 and 63, on studs projecting from the inner side of the base extension la. The movement of the gears 63 and 69 is synchronized withthe movement of the rolls 24 so that the levers 53 and 59 after completing the cycle of operations set forth above are picked up by the pins 1| and 12 and are returned'to their original positions, as shown in Fig. 9. Prior to the elevation by the pins 1| and 12 of the arms 56 and 51 to their normal elevated positions, the plates 42 and 43 are cleared by the roll 24 passing therebetween and-are therefore permitted to return to their normal elevated positions, this return movement of the plates being effected through the medium of suitable springs (not shown) associated preferably with the plate hinges 45 and 46. This elevation of the plates 42 and 43 permits the hook elements 54 and 55 to return to their operative positions with respect to the arms 56 and 51, so that as these arms are elevated by the pins 1| and 12 as set forth, they are again engaged by the retaining hooks 54 and 55 It will be noted by reference to Fig. 13 that the arm 51 of the lever 59 is engaged by the pin 12 in advance of the engagement of the pin 1| with the arm 56 of the lever 53, so that the lever 59 positioning of the label on the plates 42 and 43,

is swung upwardly away from the roll while the brush 63 of the lever 58 is completing the operation of bringing the adhesive coated end of the label into the overlapping relation with the other end thereof. It will be noted further that in the upward movement of the pin I2 in engagement with the arm 51, the movement of the lever 59 is sufficient to bring the pad 55 into contact with the face of the adhesive roller 66, whereby following each cycle of operations as described, this pad is provided with a new supply of the adhesive. Fig. 9 shows the position of rest of the parts described above following each cycle of operations.

During the cycle of operations described above, the paper roll supporting pins 9 of the rotating head 6 engage the high part of the cam 4 and are thereby held in the advanced or roll-supporting position. Following completion of the labelapplying operation, the cam rollers I4 of the pins pass into the low portion of the cam 4, as shown at the bottom of Fig. 1, which permits the springs I3 to retract the pins 9 sufficiently to release the labeled rolls. At the point of withdrawal of the pins 9, the rolls have progressed to a point in which the inner face of the roll lies in contact with a pair of segmental plates 16 and 11, see Fig. 2, which are supported on brackets I8 and I9 respectively secured to the face plate and to a structural member 8I supported on the base I. When, therefore, the pin 9 is retracted as set forth, the roll supported thereby is stripped from the pin by the plates I6 and 11, which permits the roll to drop downwardly upon a conveyer 82, which is shown in the present instance as operating at one end on a roller 83 journaled in the structural member 8I and at the opposite end in a corresponding structural member 84 supported on the base I. In dropping downwardly toward the conveyer, the end of the roll which has been in engagement with the plates I6 and I1 comes in contact with a bar 85, which causes the roll to assume an upright position on the conveyer 82, as indicated at 86 in Figs. 1 and 2. The labeled rolls are conducted successively by the conveyer 82 to a packing station or to any desired point of discharge.

The mechanism by which the labels are fed into position above the plates 42 and 43 is illustrated in Figs. 1, 2, and 4 to '7, inclusive. Provision is made on the base extension Ia for rotatively supporting a roll 81 of printed labels forming a continuous strip. The character of this strip is illustrated in Fig. 7, wherein the dividing lines between successive labels are indicated by the broken lines 88. Formed in this strip and on each dividing line 88 is a pair of adjacent apertures 89, which pairs of apertures are staggered with respect to the longitudinal edges of the strip as shown. These apertures are adapted for reception of pins 9I projecting from the periphery of a feed roll 92 journaled in the base extension Ia, to which roll the labeled strip 93 is guided by an idler pulley 94. The shaft of the roll 92 carries a sprocket 95, see Fig. 5 which is connected by a suitable chain 95 with a sprocket 91 at one end of a shaft 98 journaled at the top of the frame extension Ia, which shaft carries a roller 99, Fig. 4, over which the labeled strip 93 passes. The shaft 98 also carries a gear IOI which meshes with a gear I02 on the shaft I03 of a superimposed roller I04 between which and the roller 99 the paper web 93 is confined as shown in Fig. 4. The roller I04 is journaled in bearings I05, Fig. 5, which are slidable in vertical guides I06 at the top of the base extension Ia, and springs I01 act on these bearings to force the roller I04 downwardly upon the web 93 and toward the roller 99 at a predetermined pressure. The gear IOI also meshes with a pinion I08 on a shaft I09 journaled in the base extension Ia, and this shaft also carries a sprocket I I I which is connected through a chain I I2 with a sprocket I I3 on a transverse shaft H4. The shaft II4, as shown in Figs. 1 and 2, is connected through helical gears I I5 with the shaft 39, which aspreviouslyset forth is intermittently operated. It will be noted, however, that by reason of the aforedescribed connection between the shaft 39 and the shaft 98, and between this latter shaft and the roll 92, both the said roll 92 and the roller 99 are actuated during such times as the shaft 39 is in operation.

The shaft I 09 which carries the pinion I08 and the sprocket III carries also an interrupted gear I I8, which in rotation meshes intermittently with a gear II'I journaled on a stud on the base extension Ia, see Fig. 5. This gear III has fixed thereto a gear II8 which meshes with a pinion II9 also journaled on a stud in the base frame, and this pinion meshes in turn with a gear I2I on the projecting end of the shaft of a roller I22. The gear I2I also meshes with a gear I23 on the shaft of a roller I24, the rollers I22 and I24 bearing the same relation to the labeled strip 93 as the rollers 99 and I04 and being similarly mounted in the base frame. It will be noted, however, that by reason of the interrupted gear II6 the actuation of the roller I22 is intermittent as regards the operation of the roller 99. As the strip 93, therefore, passes between these rollers and during the periods of inoperation of the roller I22, a free loop will be formed in the strip 93 between the sets of rollers, as illustrated in broken lines in Fig. 4.

Journaled in the frame la in alignment with the sets of rollers 99-I04 and I22I24 is a third set of rollers I25 and I26, the roller I25 being operatively connected with the roller I22 through an idler gear I2I journaled on a stud in the frame, so that the movement of the rollers I25 and I26 is synchronized with that of the rollers I22 and I24. Intermediate the last-named sets of rollers and in the path of the strip 93 is a strip-severing device, this device in the present instance consisting of a fixed shear blade I28 and a movable blade I29, Fig. 4, this movable blade being carried at the top of a yoke I3I which extends transversely across the base extension Ia and has at each side a depending portion I32 slidably supported in guides I33 and each having at its lower end a roller which engages in the groove I34 of a cam I35, these cams I35 as shown in Figs. 1 and 5 being carried by the transverse shaft II4. Rotation of the shaft 4' and of the cams I35 effects a reciprocation of the yoke I3I and of the shear blade I29. This action of the shear severing the strip 93 is synchronized with the movement of the strip-feeding elements so that the severing operation takes place during the period when by reason of the interrupted gear IIG the feed rolls I22 and I25 are stationary.

It will be noted also with reference to Fig. 1 that the shaft of the roller I25 has fixed thereto at one end a sprocket I36 which is connected through a chain I3I with a sprocket I38. This sprocket is operatively connected through a suitable gear train, including gears I39 and MI, with the adhesive-applying roller 56 previously described. By this means the roller is given an intermittent operation synchronized with the movements of the other associated parts of the mechanism.

Secured to one end of the shaft of the roller I26 is a-gear I42, and this gear meshes with a pinion I43 on a shaft I44 suitably journaled in the base frame Ia. This shaft also carries a pinion I45 which meshes with a pinion I46 on a shaft I 41 journaled in the base frame above and in parallel relation with the shaft I44. The shafts I44 and I41 carry spaced sets of pulleys I48, the pulleys of one shaft directly overlying respectively the pulleys of the other shaft. Operating on these pulleys are belts I49 and II, the outer ends of these belts passing around pulleys I52 which are journaled on transverse shafts I53 and I54 which correspond with the shafts I44 and I41 which carry the pulleys I48. As shown in Fig. 9, the two upper belts I49 occupy positions entirely above the normal horizontal plane of the hinge plates 42 and 43 and of the table plates I55 and I56 to which the said plates 42 and 43 are respectively connected. The two belts I5I are so arranged that their upper runs pass over the tops of the table plates I55 and I56, while their lower runs occupy a position below these plates. The upper run of the belts I5I and the lower run of the belts I49 are spaced apart so that the opposite edges of the severed labels 44 are loosely confined therebetween, and so that as the individual labels, are cut from the strip they are passed by the rollers I25 and I26 between the belts I49 and I5I, which function to advance the labels to a position overlying the plates 42 and 43 and centrally of the path of the rolls 24 as they pass downwardly towards these plates. As the labels are advanced into position by the belts I 49 and I5I, they engage stops I51 on the plates I55 and I56 which position the label properly with respect to the downwardly moving rolls 24, and the looseness of the belts permits the label to lie in this position undisturbed. This looseness also permits the ends of the labels to be withdrawn from between the belts transversely, as shown in Fig. 10, as the roll 24 moves downwardly as previously described.

With reference to Fig. 7, .it will be noted that in the operations as previously set forth, the individual labels are severed accurately on the lines 88, so' that the openings 89 on these lines are bisected. In the finishedroll, as shown in Fig.

15, the bisected apertures 89 form at opposite edges of the label spaced recesses 89a which de-' fine therebetween a free tab I58 which may be readily grasped by the fingers for removing the label from the roll when the latter is to be placed in use. These labels preferably are made in accordance with the principles set forth in my copending application Serial Number 687,355, filed August 29, 1933.

The operation of the machine will be readily understood from the foregoing description, and it will be understood that there may be some modification in the structural details of the machine without departure from the invention as defined in the a ended claims. While the illustrations have been confined to application to rolls of labels not exceeding in width the length of rolls, it will be apparent that a machine of the character described may be used to apply wrappers of greater width, the projecting ends of which are subsequently folded or tucked in against the ends of the roll.
